Question

A 60.0-kg skier coasts up a snow-covered hill that makes an
angle of 23.5 ° with the horizontal. The initial speed of the skier
is 9.17 m/s. After coasting a distance of 1.45 m up the slope, the
speed of the skier is 3.65 m/s. **(a)** Find the work
done by the kinetic frictional force that acts on the skis.
**(b)** What is the magnitude of the kinetic
frictional force?

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking .

An extreme skier, starting from rest, coasts down a mountain
slope that makes an angle of 25.0° with the horizontal. The
coefficient of kinetic friction between her skis and the snow is
0.200. She coasts down a distance of 12.7 m before coming to the
edge of a cliff. Without slowing down, she skis off the cliff and
lands downhill at a point whose vertical distance is 3.30 m below
the edge. How fast is she going just before she...

A 62.0-kg skier is moving at 6.10 m/s on a frictionless,
horizontal, snow-covered plateau when she encounters a rough patch
4.10 m long. The coefficient of kinetic friction between this patch
and her skis is 0.300. After crossing the rough patch and returning
to friction-free snow, she skis down an icy, frictionless hill 2.50
m high.
a) How fast is the skier moving when she gets to the bottom of
the hill?
b)How much internal energy was generated in crossing...

A 66.5 kg skier is moving at 6.80 m/s on a frictionless,
horizontal snow-covered plateau when she encounters a rough patch
3.90 m long. The coefficient of kinetic friction between this patch
and her skis is 0.330. After crossing the rough patch and returning
to friction-free snow, she skis down an icy, frictionless hill 2.85
m high.
Part A. How fast is the skier moving when she gets to the bottom
of the hill?
Part B. How much internal energy...

A child slides down a snow‑covered slope on a sled. At the top
of the slope, her mother gives her a push to start her off with a
speed of 0.85 m/s. The frictional force acting on the sled is
one‑fifth of the combined weight of the child and the sled. If she
travels for a distance of 23.5 m and her speed at the bottom is
3.75 m/s, calculate the angle that the slope makes with the
horizontal.

1. A 85.0-kg speed skier has finished a long down hill race and
reaches a final slope (fig. 1 below) designed to slow her down. At
the bottom of this slope her speed is 29.0 m/s. She slides up the
inclined plane of snow on her skis and at a certain vertical height
h has speed 1.95 m/s. The force of friction between her skis and
the snow does work of magnitude 3995.0 J . (Ignore air friction.)
(a) What...

A 50.0-kg skier starting from rest travels 200 m down a hill
that has a 60.0° slope and a uniform surface. When the skier
reaches the bottom of the hill, her speed is 20.0 m/s. What is the
magnitude of the friction force if the skier travels directly down
the hill? Please show work. A. 375 N B. 55.3 N C. 89.4 N D. 50.0 N
E. 20.7 N

A 41.0-kg skier with an initial speed of 1.5 X 101 m/s coasts up
a 2.50-m-high rise as shown below. The coefficient of friction
between her skis and the snow is 0.0800. a) Where do you define the
gravitational potential energy Ug to equal 0 J? b) If the skier has
energy at the bottom of the hill state what kind it is and
determine its value. c) If the skier reaches the top of the hill
what kind of...

A skier is pulled up a slope at a constant velocity by a tow
bar. The slope is inclined at 21.3 ° with respect to the
horizontal. The force applied to the skier by the tow bar is
parallel to the slope. The skier's mass is 45.7 kg, and the
coefficient of kinetic friction between the skis and the snow is
0.212. Find the magnitude of the force that the tow bar exerts on
the skier.

A resort uses a rope to pull a 55-kg skier up a 37 ∘ slope at
constant speed for 180 m . The coefficient of kinetic friction
between snow and skis is μk = 0.18.
A) Calculate the tension in the rope.
B) How much work does the rope do on the skier?

A 90 kg skier starts from the top of a hill with a 19 deg slope.
The skier reaches the bottom of the slope 11 s later.
a) If there is a constant friction force of 70 N which resists
his motion, how long must be the incline of the hill?
b) Draw a force diagram for the skier with labels and
magnitudes.
c) What is the coefficient of kinetic friction between the block
and ramp?
d) How much work...
